In the present study saddle joints of the thumb and neighboring joints of 100 anatomic specimens are examined with regard to radiological and macroscopic arthrotic alterations. Comparisons of radiological and macroscopic findings demonstrate that early arthrotic articular alterations cannot be diagnosed radiologically. Almost half of the hands examined displayed arthrotic lesions in the saddle joint of the thumb, whereas the trapezoido-scaphoidal and trapezio-scaphoidal joints are each affected in one third. Hands with manifest thumb saddle joint arthrosis are accompanied by arthrotic alterations of the joints between the scaphoid, trapezium and trapezoid in two-thirds of the cases. In the remaining radial intercarpal joints, no macroscopic evidence can be ascertained of arthrotic alterations. Among the processes discussed as causal factors of simultaneous incidence of scaphoidal and carpo-metacarpal arthroses, the architecture of the osseous carpus, the individual expression of the scaphoid bone and poly- or secondary arthrotic processes are important.
在本研究中，对100个解剖标本的拇指鞍状关节及相邻关节进行了放射学和宏观关节改变方面的检查。放射学和宏观检查结果的比较表明，早期关节软骨改变无法通过放射学诊断。几乎一半接受检查的手部在拇指鞍状关节出现关节病变，而大多角骨 - 舟状骨关节和小多角骨 - 舟状骨关节分别有三分之一受到影响。有明显拇指鞍状关节关节炎的手部，三分之二伴有舟状骨、大多角骨和小多角骨之间关节的关节改变。在其余的桡腕关节中，未发现宏观上的关节改变迹象。在讨论为舟状骨和腕掌关节同时发病的病因因素中，腕骨的结构、舟状骨的个体表现以及多关节或继发性关节病变过程很重要。
